Objective 2: Study and evaluation of Software Defined Networking for hybrid heterogeneous networks

Motivation

In hybrid (wired/wireless), heterogeneous (multiple-technology) access environments, SDN can address several key challenges including the support of a flexible set of rules and actions to reduce the effects of delay and disruption that are typical of wireless segments, by enabling capacity sharing across multiple links and improving internetwork compatibility. At the same time, worldwide energy consumption has become a key social and political issue and Internet traffic starts to have a significant impact on it, given its steady growth due to the increasing number of users and higher service demands.

In this objective, an SDN-based architecture in hybrid (wired/wireless) heterogeneous (multiple-technology) access networks is analysed, focused on resource allocation and routing using information such as mobile user location forecast and traffic load prediction.
